摘要： This invention provides processes and systems for converting biomass into high-carbon biogenic reagents that are suitable for a variety of commercial applications. Some embodiments employ pyrolysis in the presence of an inert gas to generate hot pyrolyzed solids, condensable vapors, and non-condensable gases, followed by separation of vapors and gases, and cooling of the hot pyrolyzed solids in the presence of the inert gas. Additives may be introduced during processing or combined with the reagent, or both. The biogenic reagent may include at least 70 wt %, 80 wt %, 90 wt %, 95 wt %, or more total carbon on a dry basis. The biogenic reagent may have an energy content of at least 12,000 Btu/lb, 13,000 Btu/lb, 14,000 Btu/lb, or 14,500 Btu/lb on a dry basis. The biogenic reagent may be formed into fine powders, or structural objects. The structural objects may have a structure and/or strength that derive from the feedstock, heat rate, and additives.

摘要： Handling of municipal solid waste (MSW) is described. A method for handling MSW in a single waste processing facility includes receiving the MSW at the waste processing facility. The MSW is separated into biomass, recyclables, and plastics. The biomass is processed at the waste processing facility to produce syngas using a gasifier. The plastics are also processed at the waste processing facility to produce naphtha, diesel fuel, and/or lubricants. Waste heat from the processing of the biomass and from the processing of the plastics is captured and used in the generating of electricity at the waste processing facility. Facilities for handling MSW are also described.
